peat - silty peat from the San Andreas fault zone, formed in a marsh that dried out roughly a century ago - large display specimen Because fulgurites are amorphousThis silty peat was collected from a former marsh along Pallett Creek in the San Andreas fault zone, Los Angeles County, California Peat is formed by partial decomposition of plant material under acidic conditions. With burial and compression, peat forms lignite and eventually bituminous coal. At Pallett Creek, the peat was formed in a marshy sag pond in the fault zone. Layers of leaves and vegetation fell into the marsh and were subsequently covered
